Subject: Another patch from Matt Kraai <kraai@alumni.carnegiemellon.edu>: > >
The following patch allows ln -n to function like GNU. It also fixes a >
typo with my previous patch to add support for ln FILE DIRECTORY. And > it
removes some code that checks the maximum length of the filenames. I > can't
figure out why that code is necessary. Anyone know? > > Matt
